Overview

Installation• With a maximum radius of 165'

(50 m), the ST-1600 rotor is designed for placement outside the field for safety and serviceability.

• Pair the rotor with the ST-1600-KIT vault system to bring all irrigation components together inside one strong enclosure for simple access to the complete system.

ImportantThe water may contain foreign objects such as sand, rocks, and other impurities, which can damage the rotor. To avoid these problems, you may need to install a filter.

After InstallationTroubleshooting non-rotation after installation:1. Check for plugged secondary nozzle.2. Check for a blocked propeller in the

turbine assembly.

ST-1600-HS-B: Replacement Parts


Servicing and Maintenance

➊

➌

A. Replacing the cover and rotor1. Remove center plug with a flat-

blade screwdriver and unscrew the nut underneath using a 1/ 2" (13 mm) socket.

B. Replacing the propeller and checking for debris1. Remove the eight screws on the

turbine housing (six large, two small).

C. Speed control adjustment 1. Turn the brass knob clockwise to

slow down rotation.

D. Servicing secondary nozzle1. Unthread the secondary nozzle.

E. Arc adjustment1. For part-circle operation, reach

inside the rotor to set the arc adjustment rings to the desired arc setting.

2. Use the gear-drive insertion/ removal tool to unscrew the rotor from the piston. The tool will grab onto the screws below the rotor.

3. Turn the wrench counterclockwise until the unit is free from the threads.

4. Lift the unit out of the body.

2. Pull to remove the propeller cover and expose the propeller.

3. Remove the propeller from the housing to clear any debris that may be trapped inside.

2. For 360° operation, remove both adjustment rings.

2. Clear any debris that may be trapped inside.
